Have you tried using other devices or PC when you were login your account? I suspected that it could be your device use and next is your internet connection. To be honest, this is a rare issue and in fact, I just now heard about this, it's totally buggy site that's why I hate using web wallet.
there's no reason you to stay on that wallet, find a better wallet and follow what they said above. Import your wallet into Electrum or any open-source wallet that supports BIP39 and it could compatible to import your seed phrase.
I'm gonna try to import my wallet and see what will happen, I'll gonna keep you guys updated.
Yes, please.
I just curious about this issue. I open my eyes to this thread.
